Description générale

Azocasein is a chromogenic derivative of casein. Protease degrades azocasein to yield TCA-soluble azopeptides with high UV-absorbance. This azocasein assay is widely employed to estimate the protease production by bacterial fermentation on synthetic substrates from glucose and inorganic salts.

Application

Azocasein has been used as a substrate for determination of protease activity.
Azocasein is a nonspecific protease substrate. Hydrolysis of the casein releases the azo dye into the media where it is detected by absorbance at 440 nm.
Azocasein is an inflammatory agent that is used to induce amyloid A amylooidosis in experimental animals.

Laboratory data on the behaviour of the pathogenic form of the prion protein (PrP(Sc)) in environmental matrices such as sewage sludge is scarce. Direct experiments with this misfolded protein require strict safety measures, pathogen class-3 facilities and costly reagents. However

The opportunistic human bacterial pathogen Pseudomonas aeruginosa produces membrane vesicles (MVs) in its surrounding environment. Several features of the P. aeruginosa MV production mechanism are still unknown. We previously observed that depletion of Opr86, which has a role in outer

To overcome the metal restriction imposed by the host's nutritional immunity, pathogenic bacteria use high metal affinity molecules called metallophores. Metallophore-mediated metal uptake pathways necessitate complex cycles of synthesis, secretion, and recovery of the metallophore across the bacterial envelope. We
